Question

The INCORRECT match in the following is :

<!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}--> JEE MAIN 2019

• A. $\Delta G^0<0,K>1$
• B. $\Delta G^0<0,K=1$
• C. $\Delta G^0<0,K<1$
• D. $\Delta G^0>0,K<1$

Answer 1

The correct option is C $\Delta G^0<0,K<1$

$\Delta G=\Delta G^0+RTlnk$

At equilibrium,

$\Rightarrow \Delta G^0=-RTlnK$

$-RTlnK<0$

$RTlnK>0$

$lnK>0$

$\Rightarrow K>1$
Hence, correct option is (a).
